If I sell my used car myself and buy another, how is Kansas sales tax figured?

Plain-English summary

Kansas Notice 24-19 explains a sales tax change made by 2024 House Bill 2098 (New Section 2 and Section 3). For years, Kansas has let a buyer subtract the value of a trade-in when figuring sales tax on a vehicle. Effective for transactions on and after January 1, 2025, the new law extends a similar break to an individual who sells a used vehicle privately rather than trading it in.

Here is how it works. If an individual (1) sells a used motor vehicle instead of trading it in, and (2) buys a new or used vehicle of greater value within 120 days before or after that sale, then Kansas sales or compensating use tax is due only on the difference between the higher price of the vehicle purchased and the amount received for the used vehicle sold. The purchase price is the "total consideration paid" -- the amount after any rebate or discount. If the vehicle purchased costs the same as or less than the amount received for the vehicle sold, no sales or use tax is due.

Only one sale and one purchase may be matched; multiple vehicle sales cannot be combined to reduce the tax on one purchase. "Motor vehicle" has the meaning in K.S.A. 8-126, which means boats, trailers, motorized bicycles, electric-assisted bicycles, and motorized wheelchairs do not qualify. Section 3 of the bill amends K.S.A. 12-199, the local compensating use tax, which continues to apply except as changed by New Section 2.

What this means for you

Individuals buying and selling vehicles

• If you sell your used vehicle yourself and buy a more expensive vehicle within 120 days (before or after the sale), you pay Kansas sales or use tax only on the price difference.
• You must document both deals with signed bills of sale -- Form TR-312, or at least the sellers' and buyers' names and addresses, the vehicle's year/make/VIN, the sale price and date, and both signatures. The sale price, sale date, and at least one buyer and seller name must match the title assignment. The Department also wants a copy of the title for each vehicle.
• Give the completed bills of sale to the county treasurer when you register the purchased vehicle, and the treasurer collects any tax due. If you already paid tax that is more than the reduced amount, apply to the Department for a refund of the excess using Form ST-21VT.
• The refund claim must be filed within three years of the purchase of the replacement vehicle. If you do not provide the signed bills of sale, tax is due on the full price.

Common questions

When does this take effect? For transactions on and after January 1, 2025.

How is the tax figured? On the difference between the higher price of the vehicle you buy and the amount you received for the used vehicle you sold. If the purchase is not greater in value, no tax is due.

Does the sale and purchase have to happen at the same time? No -- the purchase must be within 120 days before or after the sale.

Can I add up several vehicles I sold? No. Only one vehicle sold may be matched to one vehicle purchased.

Do boats or trailers count? No. "Motor vehicle" follows K.S.A. 8-126, which excludes boats, trailers, motorized bicycles, electric-assisted bicycles, and motorized wheelchairs.

How do I get a refund if I already paid? File Form ST-21VT with the signed bills of sale, within three years of the purchase.

                          USED MOTOR VEHICLE SALES TRANSACTIONS

                                   (NOVEMBER 21, 2024)

  During the 2024 Legislative Session House Bill 2098 was passed and signed into law. New

Section 2 and Section 3 of the Bill address the sales and use tax treatment of certain used motor
vehicle sales transactions.

   For purposes of the New Sections 2 and 3, the term "motor vehicle" has the same meaning

as that found in K.S.A. 8-126. K.S.A. 8-126(ss) provides:

         (ss) "Vehicle" means every device in, upon or by which any person or property
   is or may be transported or drawn upon a public highway, excepting electric personal
   assistive mobility devices or devices moved by human power or used exclusively upon
   stationary rails or tracks.

K.S.A. 8-126(w) provides:

         (w) "Motor vehicle" means every vehicle, other than a motorized bicycle,
   electric-assisted bicycle or a motorized wheelchair, that is self-propelled.

Based on those definitions, the term "motor vehicle" does not include boats, trailers, motorized
bicycle, electric-assisted bicycle or a motorized wheelchair, that is self-propelled.

 New Section 2(a) provides, effective for transactions occurring on and after January 1, 2025,

when:

   (1)   a used motor vehicle is sold by an individual, instead of being traded in by the
         individual as a partial payment on the sale of a new or used motor vehicle, and

   (2)   the individual purchases a new or used vehicle of greater value within 120 days
         before or after such sale,

then Kansas sales or compensating use tax shall be paid only on the difference between the higher
price of the new vehicle and the amount received for the used vehicle sold by the individual. The
price of the new vehicle is based on the "total consideration paid" for the vehicle which, in
accordance with New Section 2(f), means the amount paid after any rebate or discount. In the
event the amount paid for the new vehicle is equal to or less than the amount the individual received
for the sale of the used vehicle, no sales or use tax will be due.

  It is important to note the New Section(s) contemplate only one vehicle being sold and one

vehicle being purchased. Sales of multiple vehicles, or multiple single vehicle sales, cannot be
used to reduce the purchase price of a new vehicle upon which sales tax is computed.

  New Section 2(b) addresses how any sales or use tax due will be paid, and how a refund of

sales or use tax may be claimed. It provides the individual may either:

 (1)   Provide to the county treasurer the completed bills of sale for the vehicle sold and
       the vehicle purchased at the time the purchased vehicle is registered. The county
       treasurer will then collect any tax due, in accordance with Section 2(a); or

 (2)   If taxes have already been paid on the purchased vehicle, and that tax is greater
       than the tax owed in accordance with Section 2(a), apply to the Department of
       Revenue for a refund of the excess tax paid by the individual, by providing both
       the completed bills of sale for the vehicle sold and the vehicle purchased.

  New Section 2(c) sets forth the documentation and information that must be provided if the

deduction for the price of the used vehicle is to be allowed. New Section 2(c)(1) provides no
deduction shall be allowed unless the taxpayer claiming the deduction provides a copy of the bills
of sale required by New Section 2(b), and such bills of sale are on Department of Revenue Form
TR-312 Bill of Sale, or, at a minimum, include information necessary to tie the specific purchase
transaction to the related sale transaction including, but not limited to, the:

 (A) Seller's printed name and address;
 (B) buyer's printed name and address;
 (C) year, make and vehicle identification number of the vehicle;
 (D) sale price and date of sale of the vehicle; and
 (E) signatures of the seller and the buyer and the date signed.

  New Section 2(c)(2) provides the sale price, date of sale and the name of at least one buyer

and seller listed on the bill of sale must match the information entered in the assignment of title on
the back of the certificate of title.

 And New Section 2(c)(3) provides that if the taxpayer claiming such deduction fails to

provide such signed bills of sale, the tax shall be due on the total consideration paid for the new or
used vehicle.

  In addition to this information, the Department of Revenue requires a copy of the title for a

vehicle being sold, and for a vehicle being purchased. County treasurers may make a similar
requirement when registering a vehicle.

  New Section 2(d) establishes a statute of limitations period for the issuance of a refund by

the Department of Revenue. It provides the Department of Revenue shall issue a refund pursuant
to subsection (b)(2) for any valid claims filed within three years from the date of the purchase of
the replacement vehicle.

New Section 2(e) requires the Director of Vehicles to prescribe forms for compliance with

New Section (2).

  New Section 2(f) provides that "consideration paid" means the amount paid after any rebate

or discount.

  Section 3 of the Bill amends K.S.A. 12-199, which imposes a local compensating use tax for

the privilege of using or storing within a city or county any vehicle that is required to be registered,
and that is purchased within Kansas but outside of the local retailers' sales taxing jurisdiction of
such city or county. The tax is imposed by every city or county imposing a retailers' sales tax.
The amended language in Section 3 indicates the provisions of Section 3 continue to apply, except
as otherwise provided in New Section 2.

 When the Director of Vehicles has prepared the necessary forms prescribed by New Section

2(e) those forms will be available through the Department of Revenue website at:
www.ksreveue.gov.

If it is necessary to claim a refund, use Form ST-21VT Request for Sales Tax Refund of a

Motor Vehicle Sold within 120 Days of a New or Used Motor Vehicle Purchase.

Motor Vehicle within 120 Days of the Purchase of a New or Used Motor Vehicle.
